Debugging Tools — BareFoot, wack, GDB Remote

Overview

Debugging Amiga programs ranges from ROM-resident kernel debuggers (wack/SAD) through software monitors to modern cross-debugging via GDB stubs.

Tool Comparison

Tool	Type	Target	Best for
BareFoot	Serial debugger	Real hardware / UAE	OS-level, Exec kernel
wack/SAD	ROM debugger	Real hardware	Boot-time, crash analysis
MonAm	Software monitor	AmigaOS	Breakpoints, disassembly
IDA Pro	Static + remote	Cross-platform	Static RE, decompilation
GDB (m68k-elf-gdb)	Cross-debugger	FS-UAE / Basilisk	Source-level C debugging
Enforcer	Memory watchdog	AmigaOS (68020+)	Illegal memory access detection
MuForce	Memory watchdog	AmigaOS (68040+)	Same as Enforcer for 040/060

Enforcer / MuForce

Detects invalid memory accesses using MMU:

Enforcer Hit!   $0000000C read by task "myapp" at $00020456

; Install:
run >NIL: Enforcer
; or for 040/060:
run >NIL: MuForce

FS-UAE GDB Debugging

# In fs-uae.conf:
remote_debugger = 1
remote_debugger_port = 6860

# Connect from host:
m68k-elf-gdb myapp
(gdb) target remote localhost:6860
(gdb) break main
(gdb) continue
